Though with my sqrt example, it's just a plain simpleWarning, which doesn't give you the opportunity to do special handling. tryCatch(sqrt(-1), warning = function(w) class(w)) ## [1] "simpleWarning" "warning" "condition" > Designing and implementing a condition class hierarchy to support this > is indeed the h...

Dear all, For an open-source project that I'm working on (1), which uses R for all its heavy lifting but includes a wrapper shell script, I was hoping to find a way to capture all warnings (and, in fact, errors too), and handle them in my own way. I realise I can do this for a single expression using something like: > f <- function(w) print(w$message) >

...for example, https://stat.ethz.ch/pipermail/r-devel/2012-October/065089.html A better way of suppressing certain conditions would be to allow them to have an identifier. (This is how MATLAB allows control over individual conditions.) The implementation ought to be fairly simple. simpleMessage, simpleWarning, and simpleError gain an id arg, which is stored in their structure. simpleMessage <- function (message, call = NULL, id = NULL) { structure( list(message = message, call = call, id = id), class = c("simpleMessage", "message", "condition") ) } I envisa...

Hello R Users, I am having difficulty deleting the last warning message in a loop so that the only warning that is produced is that from the most recent line of code. I have tried options(warn=1), rm(last.warning), and resetting the last.warning using something like: > warning("Resetting warning message") This problem has been addressed in a previous listserve string,

I am running R as an invisible subprocess in another program (RExcel). Using try I can catch errors and print the errors produced by an R statement. Is there a way to know if running a statement caused a warning message? last.warning gives me the last warning, but I do not have any indication what the statement was that caused the message. I can of course store last warning before I run a

Hi, I am running a simulation study with the survival::coxph. Some of the simulations result in problematic fits due to flat partial likelihood. So, you get the warning message: Warning message: In fitter(X, Y, strats, offset, init, control, weights = weights, ... : Loglik converged before variable 2 ; beta may be infinite. How can I keep track of the simulations which yield any kind of

Here are the details to get this working: 1.

Setup a method to generate such a condition similar to warning() and stop(): exit <- function(...) { invisible(signalCondition(simpl...

Not desperately important, but nice to have and possibly of use to others, is the ability to suppress specific warnings rather than suppressing warnings indiscriminately. I often know of a specific warning that I want to ignore (because I know that's it's a false positive/ignorable), but the current design of suppressWarnings() forces me to ignore *any* warnings coming from the

Hello, I have a problem to handle the following statements. for(i in [1:3]) { file=paste("file", i, ".dat") bb <- read.table(file) x11() plot(bb) dev.off() } When the input .dat file is empty, the program stops running and an error message appears. Could someone tell me how to handle this exception? Thanks

Hi, I used to use reshape and moved to reshape2 (R 2.15.1). Now I tried some of my older scripts and was surprised that my cast function wasn't working like before. What I did/want to do: 1) Melt a dataframe based on a vector specifying column names as measure.vars. Thats working so far: dfm <- melt(df, measure.vars=n, variable_name = "species", na.rm = FALSE) 2) Recast the
